Document Summary
Summary table tallies values as frequencies/percentages for each category: see difference amongst categories. Contingency table cross-tabulates/tallies jointly values of two or more categorical variables can study patterns that may exist between variables. Relative frequency distribution relative frequency/proportion of the total for each group that each class represents. Percentage distribution percentage of the total each group represents. Cumulative percentage distribution presenting information about the percentage of values that are less than a specific amount; as class intervals increase, add percentages to accumulate, finally reaching 100% Pie chart uses parts of a circle to represent the tallies of each category: size of each part/slice varies according to the percentage in each category. Can quickly see main important categories contributors to incomplete atm transactions (accumulative frequency of first 2 =82. 5% steep gradient of line) Side-by-side bar chart uses sets of bars to show the joint responses from two categorical variables.
